atomoxetine was the most effective treatment for improving my executive functioning, i was on it for a couple months at 80mg. The last week of the last month i had a panic attack almost every day, which i believe was because of the stratterra. At least that's what i chalked it up to, i would have spells lasting an hour or more of feeling like i could barely breath, and severe tachycardia, usually after i had taken the pill in the morning. Near the end i would get a second attack in the evening. It frightened me so much i stopped taking it. A couple months earlier i was on half the dosage, with little to no effect. This was when i was trying to treat ADD, before i found out i had been informally diagnosed with Aspergers as a child, and researching found this diagnosis was more spot on for all my peculiarities. As far as sleep, i had a hard time getting to bed while taking atomoxetine, so i was prescribed trazadone in conjunction, which worked for the most part, but i would occasionally do and say things before knocking out, which i had no recollection of when my wife told me about it later. Not that i did anything terribly strange, it just really bothers me that i had no memory of them.
